Product Description

The FAG NU205-E-XL-M1 is a single-row cylindrical roller bearing with a brass cage, designed for high radial load capacity, rigidity, and reliable performance at higher operating speeds. The cage reduces roller-to-roller contact, helping the bearing run cooler and faster than full-complement cylindrical roller bearings, while the separable ring design makes installation and maintenance easier.

As an NU design, it supports radial loads only and is widely used as a floating (non-locating) bearing, allowing axial displacement of the shaft relative to the housing in both directions to compensate for thermal expansion. When combined with HJ angle rings (sold separately), it can also function as a support bearing to handle axial loads in one direction.

As part of FAG’s X-life range, it offers improved internal geometry and materials, enabling longer service life, higher performance, reduced heat generation, and extended maintenance intervals compared to standard cylindrical roller bearings.
